can matter change its state class 9

by Leone Wuckert Published 3 years ago Updated 2 years ago

Matters can be changed from one state to another state. A solid can be changed into liquid and a liquid can be changed into gas. Most of the metals, which are solid, turn into liquid on heating and turn into vapor on further heating.

Can matter change its state?

Matter is present everywhere around s and we notice that some of the matter can transform its physical state by going through some of the physical processes. So this gives rise to an interesting question – can matter change its state?

Does every object in existence undergoes a state change?

It will interest you to know that every object in existence undergoes a state change. It is only a question of the amount of heat supplied to the substance. If you supply enough heat, everything on this planet can be made to change its state. The thing is though not every substance has to follow the solid-liquid-gas path.

What are the two main types of changes in matter?

Generally, matter experiences two main types of changes: chemical change and physical change. In the process of physical change, there is no alteration in the natural identity of the matter, though the change in its state, size, and shape occurs.

What are the 5 changes of State?

Common changes of the state include melting, freezing, sublimation, deposition, condensation, and vaporization. These changes are shown in the figure given below. Why do Phase Changes Occur?

Can matter can change States?

Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid). This change is called MELTING. If water is heated, it changes to steam (a gas).

Can matter change its state answer Class 9?

The answer is 'Yes'. It can definitely change its shape, size, and volume. For examples, water turns into ice upon freezing, here the form of water converts from the liquid state into the solid state; the matter itself doesn't change but it transforms its shape.

How can matter change its state short answer?

Answer. Matter can change its state by cooling or heating.

Can matter is changed?

Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

Can matter change its state Byjus?

They are reversible changes and do not involve any changes in the chemical makeup of the matter. Common changes of the state include melting, freezing, sublimation, deposition, condensation, and vaporization.

How we can change the state of matter?

We can change a solid into a liquid or gas by changing its temperature. This is known as changing its state. Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up.

How can we change the state of any matter explain with an example?

One of the easiest examples of change of state can be found in your freezer. If you have ice cubes in your freezer and you take them out, they will start melting, because of the room temperature. If you boil water for example in a pressure cooker, the steam that goes out is gas.

What happens inside the matter during this change of state Class 9?

Expert-verified answer When the physical state of matter changes, the intermolecular forces between particles also changes that results in change in intermolecular distance between particles. Like during melting of solid to liquid, intermolecular forces decreases that increase the distance between particles.

How does matter change its state state an example from your daily life?

Heat melts ice and changes it to liquid water. Metals can be changed from a solid to a liquid state also. Metals must be heated to a high temperature to melt.

Why does matter change its state every now and then?

Changes of state are physical changes. They occur when matter absorbs or loses energy. Processes in which matter changes between liquid and solid states are freezing and melting. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation.

What is matter in chemistry class 9?

1. Matter- Matter is anything which occupies space and has mass is called matter. Air and water, sugar and sand, hydrogen and oxygen etc. Matter is made up of very small tiny particles.

When solids reach their melting point, what do they become?

Solids transform into liquid when they reach their melting point.

What is the boiling point?

Boiling point is defined as a temperature at which a pure liquid changes into a gas.

What is the melting point?

The melting point is defined as the temperature at which the solid starts to melt.

What is the process in which solids directly transform into a gas?

Sublimation is defined as the process in which the solid-state changes to a gaseous state without changing into a liquid state.

What is evaporation?

When the liquid gets converted to gas at all the temperatures, it is known as evaporation.

What is Matter?

Matter is a substance that possesses mass and occupies space. Chemistry studies it, and this study has various aspects and one of the important aspects is its classification depending on its chemical composition into three main categories i.e. elements, compounds, and mixtures.

Can Matter Change Its Shape?

The answer is ‘Yes’. It can definitely change its shape, size, and volume. For examples, water turns into ice upon freezing, here the form of water converts from the liquid state into the solid state; the matter itself doesn’t change but it transforms its shape. The components of water remain the same just the shape changes.

Question For You

Q1. Which of the following process converts solid form of matter to a gaseous form?

What is a change of state?

A change of state is a physical change in a matter. They are reversible changes and do not involve any changes in the chemical makeup of the matter. Common changes of the state include melting, freezing, sublimation, deposition, condensation, and vaporization. These changes are shown in the figure given below.

What is the process of a solid changing to a liquid called?

The process in which a solids change to a liquid is called melting. The melting point is the temperature at which a solids change to a liquid.

What happens to the molecules when the temperature increases?

When the temperature or pressure increases, the interaction between the molecules increases. Similarly, when the temperature decreases, it is easier for molecules and atoms to settle into a more rigid structure. Freezing Melting Vaporization Condensation Sublimation Questions.

What is the process of a liquid boiling and changing to a gas called?

The bubbles rise through the water and escape from the pot as steam. The process in which a liquid boils and changes to a gas is called vaporization. The temperature at which a liquid boils is its boiling point.

What happens when you fill a pot with cold tap water and heat it on a hot stovetop?

If you fill a pot with cold tap water and heat it on a hot stovetop, the water heats up. Heat energy travels from the stovetop to the pot, and the water absorbs the energy from the pot. What happens to the water next?

What is the process of liquid water changing to solid ice called?

This way liquid water is changed into solid ice. The process of liquid water changing to solid ice is termed as freezing. The temperature at which it occurs is known as the freezing point.

When a substance absorbs energy, the atoms and molecules move more rapidly?

When a substance absorbs energy the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough, that they change form. This energy is usually heat or thermal energy. In this article, let us understand the science behind the changing states of matter.

What happens to the particles of a liquid when it is heated?

When a liquid is heated,the heat energy makes its particle move even faster.At the boiling point the particles of a liquid have sufficient kinetic energy to overcome the forces of attraction holding them together and separate into individual particles.

What is the process of a solid substance changing into a liquid?

The process in which a solid substance changes into a liquid on heating is called Melting or fusion. The temperature at which a solid substance melts and changes into a liquid at atmospheric pressure is called melting point of the substance.

What happens when a solid is heated?

When a solid substance is heated,the heat energy makes its particles vibrate more vigorously.At the melting point,the particles of a solid have sufficient kinetic energy to overcome the strong forces of attraction holding them in fixed positions and break to form small groups of particles.And the solid melts to form a liquid.

What is the melting point of ice?

For Ex:The ice melts at a temperature of 0°C to form liquid water.So the melting point of ice is 0°C. Different solids have different melting points. Higher the melting point of solid substance,greater will be the forces of attraction between its particles.
